UNITE STATES WILLIAM DALTON, OF SCHENECTADY, NEW YORK.

Ralf. FASTENER.

Application filed July 24, 1925.

This invention relates to improved means for securing railroad rails to metal ties, and consists in the hereinafter described modifications of the means disclosed and claimed in my Patent No.1,512f158, Re. No. 16,023, of March 17 1925, and in my Patent No. 1,516,085, of November 18, 1921.

In the embodiment of the present invention, I preferably use the tie of special rolled T-section, provided with bulges beneath the longitudinal edges of its head, and the short hook-shaped bolts, adapted to engage around said bulges to clamp the retainer bars to the ties, disclosed and clailmed in my Patent No. 1,516,085, aforesa1 In the present instance, however, I make use of retainer bars which are recessed or undercut on one side, said recess being used to overlap the rail flange on the inside of the rail, while the same bar, when used on the outside of the rail, is turned to present its plane vertical side to the rail flange,- the recessed side being away from the rail and being used to accommodate a triangular or wedge-shaped locking member, provided with a chisel edge to bite into the tie which serves to positively secure said outside bar to the tie.

This is an important feature, because the bar on the outside is the one which must be securely fastened to prevent spreading of the rails, and the wave action, induced in the rails by the wheels, has been found to sometimes pry loose outside bars which overlap the rail flange. According to the present invention, the outside retainer bar, because it presents a vertical face to the rail flange, cannotbe loosened by the wave action in the rail. But, on the inside of the rail, as stated, the'recessed side of the bar overlaps the rail flange. Also as stated, the outside bar may have placed in its recessed side, a triangular, or wedge-shaped locking member, havinga chisel edge which can be driven into the metal of the top of the tie and held there by the clamping action of the retaining bolts. These bolt-secured retainer bars can be used with or without an interposed insulating pad, as desired. Inasmuch as both the outside and inside bars are adjustable, according to the present invention, it is unnecessary to make the top of the recess, which is to overlap the flange, at a greater inclination to the horizontal than the top of said flange, as claimed in my pat-.

Serial No. 45,814.

not only by the bolts, which cause a frictional resistance of about 8,000 lbs, but also by the positive engagement of the wedgeshaped locking member with the tie.

The invention is illustrated in the accompanying drawing, in which,

Figure 1 is a side elevation of a tie with the rails secured thereto;

Figure 2 is a plan View of one of the rails and its fasteners applied to the tie;

Figure 3 is a cross-section of the tie showing a rail fastener and taken on line 83 of Figure 1;

Figure 4 is a view like the right hand part of Fig. 1 but on a larger scale, and

Figure 5 is a similar view showing the use of an insulating pad.

In these views, the tie 1 is of T section and has the bulges 3 along the underside of the edges of its head 2, as in my said prior Patent No. 1,516,085. It is also shown as having secured to its ends the stabilizing angle plat-es 5, which are claimed in my arior application, filed June 1, 1925, as Serial No. 34,021. The rails 4 are secured to the tie by the retainer bars 6 and bolts 7, having hook-shaped heads 8, engaging around said bulges, as in said Patent No. 1,516,085.

As stated above, the retainer bars 6 are identical in shape, being provided with an undercut recess 9 on one side and with holes near their ends for the bots 7. In their application, however. the bars are reversed, so that on the outside of the rail, the recessed side is away from the rail flange while, on the inside, it is towards the rail and overlaps the flange. This appears very clearly in Figure 1 and the reason for this arrangement has been hereinbefore fully set forth.

To assist in securing the bar 6 on the outside rigidly to the tie, I provide a wedge shaped or triangular locking member 10, which occupies the undercut recess of said ties to receive them. In Figure an insulating pad 12 is shown as interposed between the rail and tie.

The object and advantages of the construction thus described having been fully explained above, it will be unnecessary to re peat them.

YVh-at I claim is:

l. A retainer bar for securing rails to metal ties, said bar being of rectangular section with one side undercut to form a recess with inclined top, and provided with bolt holes near its ends; said recess being adapted to overlap the rail flange on the inside; a sharp-edged locking member adapted to occupy said recess in the bar used on the outside of the rail, so as to be forced into the tie as the bar is clamped down; and bolts adapted to be passed through said holes and be engaged under a part of the tie to secure the bars in place.

2. A retainer bar for holding rails to metal ties, having the lower portion of one of its sides recessed; a wedge-shaped locking member, having a chisel edge, adapted to occupy said recess with said edge in contact with the tie, 2 id means to clamp the bar to the tie.

3. ltteans for adjustahly securing rails to metal ties having a head and a web, without any cutting or punching of the ties, comprising bars having bolt holes near their ends, and an undercut recess on one side, hook-shaped bolts adapted to engage under the edges of the tie head and be passed through said holes, the recess in the bar on the inside of the ra'i being adapted to overlap the rail flange, and the bar on the out side of the rail presenting its plane vertical s de to the flange with its recessed side away from the rail, and a wedge-shaped locking member adapted to occupy said last mentioned recess and be forced into the metal ot the tie.

1-. Means for adjustably and removably securing rails to metal ties. comprising a retainer bar on each side of the rail, bolts For clamping said bars to the tie, the bar on the inside (Wei-lapping the rail flange and the bar on the outside presenting a p ane Vertical :tace to the rail flange, and means between said outside bar and the tie to resist lateral thrust.

In testimony whereof I have hereunto set my hand.

' XVILLIAM DALTON.
